Small diameter of the flange

Small diameter flange generally lower than the casting flange carbon is not easy to rust, forging good streamline, organization is compact, mechanical performance is superior to the casting flange; Improper forging technology also can appear grain big or uneven, solidification cracking phenomenon, higher than the casting flange forging cost. Die forging productivity is high, the operation is simple, easy to realize mechanization and automation. High precision die forgings size, small machining allowance, forgings of fibrous tissue distribution is more reasonable, can further improve the service life of parts.
